What is Voltage? The required amount of energy to move the unit charge from one point to another is known as Voltage. In other words, Voltage is the potential difference force between two points in an electric field which causes current to flow in the circuit i.e. voltage is the main cause and current is the effect. Voltage is the effect of electromotive force (EMF) and represented by

Solution. We start by making a circuit diagram, as in Figure (PageIndex{7}), showing the resistors, the current, (I), the battery and the battery arrow.Note that since this is a closed circuit with only one path, the current through the battery, (I), is the same as the current through the two resistors.
